Virginie Letschert is a policy researcher at Lawrence Berkeley National Laboratory with over two decades of experience in efficiency policy and international program development. At Berkeley Lab, Virginie leads international collaborations and technical assistance activities, working closely with experts and policymakers to raise the ambition of efficiency programs and support the development of advanced energy pathways around the world.
In recent years, Virginie has been a key expert supporting federal agencies and philanthropic foundations to advance cooling and industrial efficiency policies in Brazil, Indonesia, Chile, and other countries. Among other achievements, Virginie led Berkeley Lab's pioneering manufacturer impact analyses to showcase the benefits of energy efficiency in Egypt and Brazil, resulting in the adoption of world-class efficiency standards which will save consumers billions of dollars while substantially reducing emissions. She has also spearheaded new research on industrial decarbonization in Indonesia that have been recognized by ministerial leadership as instrumental for energy policy development.
Virginie has led technical assistance activities across multiple countries including Indonesia, Chile, Argentina, Thailand, and Tunisia, and supported activities in South Africa, Mexico, and Central America. In addition, Virginie's technical analyses have supported the development and prioritization of U.S. appliance efficiency standards for the Department of Energy. Virginie is the lead developer of LBNL's PAMS model and one of the key developers of the DREAM framework, which she has used to provide energy modeling trainings for key country partners. Her early research is foundational to Berkeley Lab's signature BUENAS model.
Virginie holds a master's in Energy and Environmental Engineering from the National Institute of Applied Sciences in France. She joined Berkeley Lab in 2004.
